I was able to copy hda to hdb (fdisk, newfs, rsync, lilo) and then use the disk originally at hdb as hda without any changes. The boot= was /dev/hda, but I used -b /dev/hdb to override that. And then in the lilo config I did: disk=/dev/hdb bios=0x80 And it wrote the boot loader to hdb so it thought that it was really hda. Jeremy C.

I was able to copy hda to hdb (fdisk, newfs, rsync, lilo) and then use the if [ $(uname) = Linux ] ; then sed 's/newfs/mkfs/' ; fi

If you use /dev/hdb as /dev/hda you must use the Floppy-Bootdisk to boot. Mount all needed partitions on /dev/hda and execute a shell. In the shell type /sbin/lilo Now it will work. I have done this several times and it works properly. remove the Floppy from the FD-Drive and reboot your system... Michelle ## Get the Power of Debian/GNU-Linux ##
Re: lilo on /dev/hdb to work as /dev/hda
I have /dev/hdb that is a mirror of /dev/hda. It is not a image copy though, so files may be in different sector/cylinder locations. I want to be able to pull the /dev/hdb and /dev/hda out; then replace /dev/hda with this /dev/hdb. So when I do this I get Lilo's L error message. It can't find the second stage boot loader. The easiest solution to this problem is to use software RAID-1 for the Thanks for the idea, but I don't want a real-time snapshot. Anyways, can lilo be used to setup a boot loader on /dev/hdb so that if you physically move it to /dev/hda and boot it will boot successfully? Again, it seems like the bios= option is not relevant, because it really will be /dev/hda. What is the most appropriate mailing list for lilo discussion? Can grub do what I want? Thanks, Jeremy C.

Anyways, can lilo be used to setup a boot loader on /dev/hdb so that if you physically move it to /dev/hda and boot it will boot successfully? Yes, this can be done. The trick is you need to tell lilo to install itself on hdb, boot the kernel on hdb, but pretend that everything is hda. The best way to do this is; mount /dev/hdb1 /mnt lilo -r /mnt -b /dev/hdb1 -M /dev/hdb where /dev/hdb1 is the hdb root partition, and you want to use a normal mbr with lilo installed in the boot record of that root partition. Again, it seems like the bios= option is not relevant, because it really will be /dev/hda. What is the most appropriate mailing list for lilo discussion? Can grub do what I want? Grub would make things a little simpler, because it delays any sort of locating of kernel etc on the disk untill boot time. It can do this because it is a whole little OS of its own that understands filesystems. Personally I find grub overkill. -- -- ABO: finger [EMAIL PROTECTED] for more info, including pgp key --

The easiest solution to this problem is to use software RAID-1 for the mirror, LILO supports this and will install itself in such a fashion that you can remove hda and have things work. A software RAID-1 can be easily split or re-added at any time, so it'll work well for a snapshot of your system if that's what you want. Russell Coker
